The alternators are necessary for the correct functioning of your automobile. They are small generators, which keep the car battery charged. Your car alternator is the part that is responsible for electrically charging the various accessories in your car. Other related parts of the charging system are the voltage regulator, the battery and the wires. These electrical generators do not last forever and being able to recognize the bad alternator symptoms which indicate an imminent alternator failure will keep you from being stuck on lonely roads.
Starting Problem (Jumps)
If your car fails to start, the car alternator might be the culprit. Another problem might be the battery, so check the charging level of the battery. The car alternator is indirectly responsible for keeping the battery charge high. When the alternator is not operating normally, the car battery voltage will drop so low that it will become impossible to start your car. If you discover bad alternator symptoms such as requiring your vehicle to be jump-started in order to make it go, or if the battery goes dead frequently, then the car alternator is usually the reason.
Dashboard Indicator
Most vehicles have a battery indicator light on their dashboard, which indicates battery life. When the light comes on properly, it means the battery is either new or properly charged and has held the electrical charges well. This also rules out any possibility of an electrical short circuit. However, if the car alternator light on your dashboard begins to flicker when you are starting your car, you need to get your car inspected for a bad alternator as soon as possible.
Alternator Belt
When the car alternator is not working properly, the turning of the car alternator belt may be affected. You can confirm this problem by removing the belt.
Battery
If your battery continuously discharges, the main reason is likely to be the alternator and you need to get it replaced.
Age of the Car
If you are driving an older car and there are frequent starting issues with it, you may have to replace a possibly worn-out alternator.
Functioning of Electrical Features
Generally, when you use any of the electrical features in your car like the radio, flashers or dashboard lights, the alternator is responsible for providing power to these items. The alternator achieves this by keeping your car battery charged. If any of the electrical features available in your car are not functioning or the lighting dims while you are driving, the car alternator might be the issue. It means the alternator is unable to produce sufficient electricity to operate all these features at their full capacity.
Noise
The car alternator consists of many parts inside that spin in order to generate an electric current. When these elements break or are worn out, the bad alternator symptoms such as the creation of noise will occur. This noise normally sounds like clanging or rattling. Therefore, you need to listen closely during the operation of the alternator in case unusual sounds are coming from the car.
Performing the Voltmeter Test
A Voltmeter is a device that measures the voltage potential of an electric circuit. If you place this voltmeter over your car battery with all the electrical features running, the pointer of the voltmeter should not exceed 13 volts. When these features are not running, you should have a voltage figure between 14 volts and 14.4 volts. Any other figures will indicate bad alternator symptoms.
